I've got both...Is the 150 worth the extra money
I started my neighbour’s 2.0L Diesel SUV the other day with the GB70 and it span over fine.As Dell says, don’t go below the GB70. I have used one to start several vehicles with smaller engines than a T6 with ease.

Be cautious storing them in the van in summer . . . dont get them too HOT. (same applies for any Lithium tech)GB70 also fits in the top of a comfort dash if you have one,that is where ours lived for a while until we put the caravelle bed in,now it lives in the bottom of there in an ikea box
